Building an iOS app using FB4.7 Premium, Air 3.4. At this point, just a very simple test framework. Suddenly, the builder is throwing PackageInspectionFailed errors, and won't complete the build. No explanation why. Simulator runs fine.

I should point out that I have been building and packaging this all day directly to my iPad with no problems. Suddenly, I'm getting this error and the app no longer builds. The last thing I did was add this line:

`text.autoSize = TextFieldAutoSize.LEFT;`

Interestingly, manually dragging the generated .ipa to iTunes and then syncing with the iPad does actually install the app, without error. It just adds a bunch more steps to my testing / debugging process.

What is this error? What are some of the conditions I should be looking for that might cause the error?
